OF TRAIN ACCIDENTS

RAILWAYS

​Railroad transportation is the primary mode of shipments and vital part of the nation's passenger transportation network. According U.S. Bureau of Transportation Statistics about 28,566 train accidents were reported from 2000 to 2008, whose damages amounted to $2,864,000 million. In response to several fatal rail accidents, the safety in railroad transportation is a highest priority for Congress of USA. Congress passed the Rail Safety Improvement Act (RSIA) of 2008, the first authorization of Federal Railroad Administration's (FRA) safety programs since 1994. Among its provisions, the most notable was the mandate requiring Positive Train Control (PTC) technology to be installed on most of the US railroad network by 2015. PTC is a system of functional requirements for monitoring and controlling train movements as an attempt to provide increased safety.

A Health Monitoring Railway System will help to the railroad transportation owners to improve thier maintenance program and meet the goals required by the RSIA:

Reducing the number and rates of accidents, incidents, injuries, and fatalities involving railroads including train collisions, derailments, and human factors.

Improving the consistency and effectiveness of enforcement and compliance programs.

Improving the identification of high-risk highway-rail grade crossings and strengthening enforcement and other methods to increase grade crossing safety.

Improving research efforts to enhance and promote railroad safety and performance.

Improving the safety of railroad bridges, tunnels, and related infrastructure to prevent accidents, incidents, injuries, and fatalities caused by catastrophic failures and other bridge and tunnel failures.
